Vortex IQ Nerve Centre tracks **24** KPI pulses for Interlink Express stores. Each metric has its own page: definition, calculation, why it matters, and what to do when it moves.

The Interlink Express connector brings the Vortex IQ **AI OS** to UK merchants shipping with the DPD UK B2B brand for premium pre-10:30 and pre-12 next-day delivery across business and consumer services. The **Nerve Centre** tracks 24 KPI pulses with hero alerts on *Avg Shipping Cost*, *On-Time Delivery Rate*, *Pre-10:30 Service Promise*, *Late Shipments*, *Exception Rate*, *Open Claims*, *Days to Token Expiry*, plus a cross-platform *Interlink OTD by Sales Channel* card and a Pre-12 SLA tracker. **Vortex Mind** investigates when premium service classes drift below the SLA line; **Ask Viq™** answers in plain English with citations back to the consignment.
